Down, Dung and Dirty
Students investigate the stages of succession in animal dung communities. They create a dung culture using fresh cow, goat or horse dung then record data on the fungal species that appear over a two week period.
Curated OER
Biomes in a Box
Students construct a three-dimensional model of a biome which illustrates the various biotic and abiotic factors unique to that biome. They use everday materials to represent the important characteristics of a particular biome and then...

Earth: The Apple of our Eye
Students are led through a demonstration in which they cut open an apple, which represents the earth. They follow through the hands-on lesson, cutting the apple into various portions--each representing some aspect of the earth.
Curated OER
Making The Geologic Time Scale Real
Students are assigned significant geologic events in Earth's history. They convert the date of the events into distances and then space themselves (on an outside playing field) away from other groups, to represent time between various...
